You can use ERC-M to directly connect to the control-boxes that have a remote-connector or to (most) any other rotators (including homebrew-systems) by use of rotorcards. Any combination of rotators is valid. Please check our Rotator-guide to clarify if you need a connector or a rotorcard.
Included with the ERC-M SMD:
Ready assembled and tested ERC-M (SMD).
DSUB-15 connector to connect the rotator(s) or rotor-card(s).
Installationguide for more than 90 rotators (including use of rotorcards).
Service-Tool (Windows XP/Vista/7/8/10 32 and 64bit) for configuration and calibration.
Rotor-Control Software (Windows XP/Vista/7/8/10 32 and 64bit)
There are no rotor-specific connectors or housing included. You will find connectors for certain rotators in the category Cables&Connectors.
Optional accesories (see category Accessories):
Desktop-housing with LCD, LEDs and keyboard
SPECIFICATION ERC-M USB
Size of printed board : 80mm x 65mm.
Supply-voltage : 12 - 14 VDC, max 10mA (without options), protected against wrong polarization or USB-powered.
Operating-temperature : 0 to 70°.
2 measuring-circuit for the rotator-feedback-voltage : 0 to +15 V, Input-Impedance > 250 KOhm.
Resolution : 10bit.
Software-driven calibration with calibration-assistant.
Dual axis interface for Azimuth only, Azimuth&Elevation or DUAL Azimuth.
Full support for rotators with overlap up to +/-180°.
Extended calibration every 5°(EL) or 30°(AZ) to compensate non-linearities of the rotator-feedback-voltage.
Security-stop, if the rotators doesn´t move within 8 sec.
Outputs-circuits :each axis has open-collector-outputs for CW(UP), CCW(DOWN), AUX(speed or brake) and AUX-reverse
Communication-port: USB with FTDI-chipset and RS232 (optional). Baudrate configurable 4800-9600-19200-38400 Baud
Controller with bootloader.
ERC is compatible to a subset of the following protocols :
Hygain DCU-1 with extension for position-feedback
Yaesu GS232A with extension for DUAL-Azimuth (by VE2DX)
Yaesu GS232B with extension for DUAL-Azimuth (by VE2DX)
Programs with which ERC-M has been checked successfully : see Software-guide
Compatible rotators (including use of rotorcards): see Rotator-guide
Firmware supported features:
delay before rotator starts moving
programmable end stops
support of overlap up to 180°
speed- or brake-function for AUX-output
speed function by angle or delay
extended Calibration azimuth every 30°, elevation every 5°
tolerance of position for tracking-mode
save and load of all calibration- and configuration-data
